Description: The 5P85 is a family of missile launch vehicles associated with the S-300 long-range air defense systems developed by the former Soviet Union in the 1970s. These 5P85 platforms serve as Transporter, Erector and Launcher (TEL) vehicles. The first version of the 5P85 (5P85ME) was introduced in 1978 in support of the S-300 missile system. The 5P85 missile launcher vehicle can be provided on wheeled or tracked chassis. The S-300V missile systems employ tracked chassis as part of their capability to be deployed almost anywhere including extreme cold climates.

The 5P85ME utilizes a 8x8 wheeled chassis to deploy four vertically launched 48N6E, 48N6E2, 5V55R and 5V55K surface-to-air missiles. The 5P85SE is a missile re-supply vehicle. Both vehicles are associated with different versions of the S-300 air defense system. The tracked chassis 5P85 can launch 9M82, 9M83 and 5V55K missiles. Each S-300 battalion/missile system includes up to 12 5P85ME missile launching vehicles.
